Buying seriously expensive companies may not always be the best idea. This rings especially true when considering that the vast majority of mergers and acquisitions struggle to integrate into the larger company. Forced to deal with added bureaucracy, culture shock, and system changes, the acquirees’ employees can begin to find themself in a foreign environment. On top of people challenges, integrations can fail due to a host of many other challenges — from inaccurate information to a leadership vacuum. In fact, the amount of M&As that fail could be nearly as high as failed innovation projects, sitting somewhere between 70% and 90%. Examples of failed mergers and acquisitions Google & Motorola and Nokia & Microsoft or Amazon & Wholefoods.
